llength &mdash; Count the number of elements in a list
<H3><A NAME="M3">SYNOPSIS</A></H3>
<B>llength </B><I>list</I><BR>
<H3><A NAME="M4">DESCRIPTION</A></H3>
Treats <I>list</I> as a list and returns a decimal string giving
the number of elements in it.
<H3><A NAME="M5">EXAMPLES</A></H3>
The result is the number of elements:
<P>
<PRE>% <B>llength</B> {a b c d e}
5
% <B>llength</B> {a b c}
3
% <B>llength</B> {}
0</PRE>
<P>
Elements are not guaranteed to be exactly words in a dictionary sense
of course, especially when quoting is used:
<P>
<PRE>% <B>llength</B> {a b {c d} e}
4
% <B>llength</B> {a b { } c d e}
6</PRE>
<P>
An empty list is not necessarily an empty string:
<P>
<PRE>% set var { }; puts &quot;[string length $var],[<B>llength</B> $var]&quot;
1,0</PRE>
